4.14 Device Power Up
The GS1559 has a recommended power supply sequence. To ensure correct
power up, power the CORE_VDD pins before the IO_VDD pins.
Device pins may also be driven prior to power up without causing damage.
To ensure that all internal registers are cleared upon power-up, the application
layer must hold the
RESET_TRST
signal LOW for a minimum of 1ms after the core
power supply has reached the minimum level specified in
DC Electrical
Characteristics on page 16
. See
Figure 4-16
.
4.15 Device Reset
In order to initialize all internal operating conditions to their default states the
application layer must hold the
RESET_TRST
signal LOW for a minimum of t
reset
=
1ms.
When held in reset, all device outputs will be driven to a high-impedance state.
